Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.
